Another example is an outer jacket, which consists of a cylindrical outer ring made of a plastic, a cylindrical middle ring made of metal and a cylindrical inner ring made of plastic. Furthermore, for example, the outer jacket may consist of an outer ring which has the shape of a regular hexagon on the outside and is cylindrical on the inside and consist of an inner ring, wherein the outer side of the inner ring is cylindrical, so that the outer ring and the inner ring form-fitting bordered each other can be.

For example, when the outer shell of the flywheel body is cylindrical, the distance of the outer side of the outer shell to the center of the flywheel body is constant. This distance is the outer radius of the cylindrical outer shell. In other words, the outer radius of a cylindrical outer shell of a rotatable flywheel body is preferably constant.

It is understood that the total diameter of the flywheel body according to the invention is thus twice the outer radius of the cylindrical outer jacket. If the outer shell is in the shape of a regular polygon, then the outer radius is the distance of one of the corners of the regular polygon and the center of the flywheel, since all the corners of a regular polygon lie on a circle, as described above.

With respect to the width of the centered ball bearing may be preferred in some embodiments, when the so-called inner ring and the outer ring of the centered ball bearing have different widths.

In a further preferred embodiment, the inner ring of the centered ball bearing also have a width which corresponds to the width of the outer shell of the flywheel ring. The width of the centered ball bearing can also be referred to as the height of the centered ball bearing or thickness of the centered ball bearing. If, for example, the outer shell of the flywheel body is cylindrical in a preferred embodiment, the width of the outer shell of the flywheel body thus corresponds to the height of the cylinder.

The present invention therefore preferably relates to a rotatable game body suitable for a children's game consisting of a between two opposite disk-shaped side caps (K1) and (K2) arranged freely rotatable flywheel body (S), wherein the flywheel body (S) has an outer jacket (M) and a Centered ball bearing (L), the first disc-shaped side cap (K1) has an outer edge (R1), an outer surface (F1) and on the inner surface (11) has a first centered extension (P1), the opposite second disc-shaped side cap (K2) an outer edge (R2), an outer surface (F2) and on the inner surface (I2) has a second centered extension (P2), and the extensions (P1) and (P2) are adapted to engage the flywheel (S), wherein the disc-shaped side caps (K1) and (K2) on the outer edge (R1) and (R2) against the freely rotatable flywheel (S) are movable to the freely rotatable swing The disc-shaped side caps have a width in the range of 0.05 times to 0.5 times the width of the flywheel body, wherein the disc-shaped side caps have a diameter in the range of 0.5 times to 1, 2 times the outer diameter of the flywheel body and the first and / or the second disk-shaped side cap is cylindrical and / or has the shape of a regular polygon, wherein the outer jacket (M) is cylindrical or has the shape of a regular polygon , wherein the outer jacket (M) of the freely rotatable flywheel body is preferably cylindrical and the outer cylindrical surface of the cylindrical flywheel body (S) is flat and printable, wherein preferably the wall thickness (W) of the cylindrical outer jacket (M) of the freely rotatable flywheel body (S ) is constant, wherein preferably, the outer radius of the cylindrical outer shell (M) of fre i rotatable flywheel (S) is constant.

In some embodiments of the inventive game body of the present invention, it may be preferable for the disk-shaped side caps to also be attached to the outer edges of the inner surfaces of the disk-shaped side caps have a plurality of projections or even one over the entire outer circumference at the outer edge to the inner surface of the disk-shaped end caps running extension, so that the disk-shaped end caps having on the outer edge a smaller distance to the freely rotatable flywheel body than the distance B ₄ and B ₅ the inner surfaces of the disc-shaped side caps to the freely rotatable flywheel body. It is particularly preferred if the distance to the freely rotatable flywheel body is at least so great that the freely rotatable flywheel body can be set in rotation and can thereby rotate freely.

According to the invention, the rotatable game body of the present invention is preferably retained by a user with a flange on the non-rotating opposite disc-shaped side caps, while with the other country of the swing body is mechanically rotated, z. B. by abutment with a finger of the other Fland. In finger gyros from the prior art, such as the finger gyros from DE 20 2017 103 662 U1, CN 107 754 323 A, CN 107 395 815 A or US 9,914,063 B1, the lateral cover caps having a diameter corresponding to the ball bearing used or minimal is greater than the diameter of the first central recess, the finger gyro must be held on these side caps, so that the rotating body can rotate freely. The finger gyroscope of the prior art often have two or three "rotor arms", wherein the diameter of the rotating body including the rotor arms is more than twice as large as the diameter of the ball bearing used of the respective finger gyro, that is more than twice as large is, than the diameter of the side covers. When holding such a finger gyro, it is essential that the rotatable body of the finger gyro is not touched with the flange, so that it can be set in rotation and rotate freely. The overall diameter of the prior art finger gyroscope is therefore limited to a maximum diameter that depends on the size of the user's area. Thus, children have smaller areas compared to adults, so that children can not use any of the prior art finger gyros to play, since their areas and fingers may be too small to hold such a finger gyro only on the side caps without the rotatable one Touching swinging body. Even if the overall diameter of the finger gyro is small enough, it is still necessary that the finger gyros of the prior art are held only in the middle of the finger gyroscope, so only on the side caps of the ball bearing to ensure the free rotation of the flywheel. This requirement can be a disadvantage in the use of such a finger gyro for motor disadvantaged or clumsy users and constitute a Flinderis. The rotatable game body of the present invention preferably has two disk-shaped side caps having a diameter which is preferably larger than the diameter of the centered ball bearing and more preferably a diameter in the range of 0.5 to 1.5 times, more preferably from 0.5 times to 1.2 times, more preferably from 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times up to 1, 4 times, more preferably from 0.8 times to 1.3 times, more preferably from 0.7 times to 1.2 times, more preferably from 0.8 times to 1.2 times, more preferably from 0.7 times times up to 1, 1 times, more preferably from 0.8 times to 1, 1 times, more preferably from 0.9 times to 1, 1 times, more preferably from 0.95 times to 1.1 times -fold, more preferably from 0.95 times to 1, 05 times the outer diameter of the flywheel body. It is therefore preferred that the disc-shaped side caps (K1) and (K2) have a diameter in the range of 0.5 to 1.5 times, more preferably 0.5 to 1.2 times, more preferably from 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times to 1.4 times, more preferably from 0.8 times 1 to 3 times, more preferably from 0.7 times to 1.2 times, more preferably from 0.8 times to 1.2 times, more preferably from 0.7 times to 1.1 times -fold, more preferably from 0.8 to 1, 1-fold, more preferably from 0.9 to 1, 1-fold, more preferably from 0.95 to 1, 1-fold, more preferably from 0.95 times to 1.05 times the outer diameter of the flywheel body (S). The rotatable game body of the present invention therefore offers the considerable advantage that it does not have to be held in such a limited predetermined place as is the case with the finger gyros of the prior art, so that the swing body can rotate freely when the finger gyroscope is held. It is particularly advantageous if the disk-shaped side caps (K1) and (K2) have a diameter in the range of 0.5 times to 1.5 times, more preferably 0.5 times to 1.2 times, more preferably of the From 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times to 1.4 times, more preferably 0.8 times up to 1.3 times, more preferably from 0.7 times to 1.2 times, more preferably from 0.8 times to 1.2 times, more preferably from 0.7 times to 1.1 times times, more preferably from 0.8 times to 1, 1 times, more preferably from 0.9 times to 1, 1 times, more preferably from 0.95 times to 1, 1 times, more preferably from 0.95 times 0.95 times to 1, 05 times the outer diameter of the flywheel body (S), since this offers the advantage that the rotatable game body can be held comfortably and easily at any point of the disc-shaped side caps, wherein the rotatable flywheel u can freely rotate freely. Thus, the rotatable toy body of the present invention offers significant advantages over the prior art finger gyros, as it is easier to handle, independent of the size of a user's area, and also for motorized or clumsy users or, in particular, for Children of all ages are easy to use. Due to these advantageous properties of the rotatable game body of the present invention is particularly suitable for children in kindergarten or primary school age.

As already mentioned above, the opposite disk-shaped side caps preferably have a distance (B ₀ ) between the two opposite disc-shaped side caps, which is the distance B ₄ between the flywheel (S) and the inner surface of the first disc-shaped side cap (K1) plus the distance B ₅ between the flywheel (S) and the inner surface of the second disc-shaped side cap (K2) plus the width (B ₃ ) of the flywheel body (S) composed. In other words, the opposite side caps preferably have a distance (B ₀ ) between the opposite disc-shaped side caps on which is greater than the width (B ₃ ) of the flywheel body (S). This is particularly advantageous when the opposing disc-shaped side caps have a diameter in the range of 0.5 to 1.5 times, more preferably 0.5 to 1.2 times, more preferably 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times to 1.4 times, more preferably from 0.8 times to 1.3 times more preferably from 0.7 times to 1, 2 times, more preferably from 0.8 times to 1.2 times, more preferably from 0.7 times to 1, 1 times, more preferably from 0.7 times 0.8 times to 1, 1 times, more preferably from 0.9 times to 1, 1 times, more preferably from 0.95 times to 1, 1 times, more preferably from 0.95 times to 1, 05 times the outer diameter of the flywheel body (S). The rotatable toy body of the present invention has the advantageous feature over the prior art finger gyros that with opposed disc-shaped side caps preferably having a diameter in the range of 0.5 to 1.5 times, more preferably 0.5 up to 1, 2 times, more preferably from 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times to 1, 4 times, more preferably from 0.8 times to 1, 3 times, more preferably from 0.7 times to 1.2 times, more preferably from 0.8 times to 1.2 times preferably from 0.7 times to 1, 1 times, more preferably from 0.8 times to 1, 1 times, more preferably from 0.9 times to 1, 1 times, more preferably from 0.95 -fold to 1, 1-fold, more preferably from 0.95 to 1, 05 times the outer diameter of the flywheel body (S) easier handling is achieved because it is not necessary, the rotatable game body as in the finger circuits of the prior art, only in a small area in relation to the total diameter of the finger gyroscope in the middle of the finger gyro, usually the caps to hold. Furthermore, it is advantageous if the opposite disc-shaped side caps have a distance B ₄ or B ₅ to the flywheel, so as to ensure that the disc-shaped side caps also on the outermost edge, the outer edge (R1) of the first disc-shaped side cap, as well the outer edge (R2) of the second disk-shaped side cap can be held without the flywheel body will touch unintentionally and the free rotation of the flywheel body is thereby prevented. In prior art finger rakes, such as those in CN 107 320 973 A, there is shown a side cover having a central recess which has a larger diameter than the ball bearing used. In the central recess of this cover, a second cap is used with centered extensions. The side covers are embedded in the outer shell of the flywheel body, therefore, in this finger gyro, the distance between the inner surfaces of the covers is smaller than the width of the rotating body. Therefore, this finger gyro has the disadvantage that it can not be held on the outer edge of the covers, as the covers and the rotatable flywheel merge into one another without height difference. Farther Care must also be taken here that the finger gyro is held in the middle of the finger gyroscope, since the covers disclosed in CN 107 320 973 A are covers which are rotatably connected to the rotating housing. Therefore, the covers in CN 107 320 973 A also have a central recess in which a second cover is used, which serves to hold the finger circle. Thus, the covers according to CN 107 320 973 A are not the non-rotating disk-shaped side caps of the rotary game body of the present invention. Furthermore, the cover according to CN 107 320 973 A is not disc-shaped side caps with flat surfaces which are particularly suitable for printing.

The disc-shaped side caps of the rotatable game body of the present invention may be made of a plastic, glass, Flolz or metals, such as aluminum, is preferred, if the disc-shaped side caps made of polypropylene (PP) and further preferably made of polyvinyl chloride (PVC), and more preferably Polyoxymethylene (POM) are made. Other non-exhaustive examples of suitable materials include metals such as cast iron, steel, stainless steel, aluminum alloys, copper alloys, magnesium alloys, titanium alloys, zinc alloys; Ceramics, such as glasses such as borosilicate glass, glass ceramic, quartz glass, soda lime glass, or technical ceramics such as silicon, silicon carbide, silicon nitride, tungsten carbide, composites such as aluminum silicon carbide, carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GRP), natural materials such as wood or bamboo , Polymers or plastics such as elastomers such as natural rubber, thermoplastics such as acrylonitrile-butadiene-styrene copolymer (ABS), cellulose acetate (CA), ionomers, polyamides such as nylon, polycarbonates (PC), polyetheretherketone (PEEK), polyethylene (PE), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polyoxymethylene (POM), polypropylene (PP), polystyrene (PS), polyurethane thermoplastics, polyvinyl chloride (PVC), Teflon (PTFE), thermosets such as epoxy resins, phenolic resins and polyesters. In some embodiments, the disc-shaped side caps may be made of different materials. In some embodiments, the disc-shaped side caps may be made of the same material. It is preferred if the disc-shaped side caps are made of the same material. In preferred embodiments, the disc-shaped side caps have a diameter greater than the diameter of the centered ball bearing, in some preferred embodiments, the disc-shaped side caps have a diameter in the range of 0.5 to 1.5 times, more preferably from 0.5 times to 1.2 times, more preferably from 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times times up to 1.4 times, more preferably from 0.8 times to 1.3 times, more preferably from 0.7 times to 1.2 times, more preferably from 0.8 times to 1.2 times more preferably from 0.7 times to 1, 1 times, more preferably from 0.8 times to 1, 1 times, more preferably from 0.9 times to 1, 1 times, more preferably of 0.95 times to 1, 1 times, more preferably 0.95 times to 1, 05 times the outer diameter of the flywheel body. It is therefore preferable when the material from which the disc-shaped side caps are made is not plastically deformed or breaks when a small compressive force engages or is applied perpendicularly to the disk-shaped side caps, particularly at the outer edges (R1 and R2) of the disc-shaped side caps, that is at the maximum distance from the center the disc-shaped side caps, that is, at a distance of the outer radius of the disc-shaped side caps is exercised. It is preferred if at least one compressive force of 50 N, more preferably at least 60 N, more preferably at least 70 N, more preferably at least 80 N, more preferably at least 90 N, even more preferably at least 100 N is necessary, around the first or second disc-shaped side cap at the outer edge (R1 or R2) of the corresponding disk-shaped side cap to bend in the direction of the flywheel, wherein the disc-shaped side caps are plastically deformed or break. It is therefore particularly preferred that the disk-shaped side caps are not plastically deformed by an applied compressive force or by an applied compressive force at the outer edge of the disc-shaped side caps below 100 N and / or not break.

This is particularly preferred when the disc-shaped side caps are made of a material in which bending of one or both disk-shaped side caps by a deflection f, which preferably maximally the distance B ₄ between the flywheel (S) and the inner surface of the first disk-shaped side cap (K1) and / or the distance B ₅ between the flywheel body (S) and the inner surface of the second disc-shaped side cap (K2) corresponds, in particular when the diameter of the disc-shaped side caps is less than or equal to the diameter of the flywheel body (S), no plastic Deformation or breakage of the material occurs. Such materials include, but are not limited to, glasses or even plastics such as PMMA or amorphous and brittle plastics or glass fiber reinforced plastics or wood which will crack under heavy use and less permanent plastic deformation as with some soft plastics or plastics Metals or metal alloys.

Force is a directed physical quantity that can be represented by a vector. For the description of a force not only its amount but also the indication of the direction in which the force acts is necessary. In addition to the magnitude and direction of the force vector, its point of application also determines the force effect. As used herein, therefore, the term "compressive force" refers to a force that acts perpendicular to the disc-shaped side caps toward the freely rotatable swing body so that the disc-shaped side caps are movable against the freely rotatable swing body. The term "compressive force" as used herein preferably refers to the force necessary to compress the disc-shaped side caps, ie to press in each case in the direction of the freely rotatable swing body, so that the freely rotatable swing body is fixed in position, wherein the fixation of The free rotating flywheel in position herein also means that a flywheel previously set in rotation is decelerated. The "pressure force" prefers on the outer edge of the disc-shaped side caps, since the amount of compressive force at the outer edge of the disc-shaped side caps to fix the freely rotatable swing body in position, is the lowest. As used herein, the term "engaging compressive force" refers to the amount of force that preferably engages the outer edge of the disc-shaped side caps, with the "engaging compressive force" preferably having a minimum amount to move the disc-shaped side caps against the freely rotatable swing body. If the amount of the applied pressure force is less than the minimum required amount to move the disk-shaped side caps against the freely rotatable flywheel body, the disk-shaped side caps are not moved against the freely rotatable flywheel body. If the amount of pressure force steadily increased until the applied pressure force reaches the minimum amount, the disk-shaped side caps are moved on the outer edge against the freely rotatable flywheel, so that the freely rotatable flywheel is fixed in position.

As used herein, the term "applied compressive force" refers to the force acting in retaining the disc-shaped side caps or compressing the disc-shaped side caps, such as when the disc-shaped side caps have been moved against the freely rotatable swing body, so that the freely rotatable swing body is fixed in position and the free rotatable flywheel remains fixed in position over a period of time. If the disk-shaped side caps are moved on the outer edge against the freely rotatable flywheel by an engaging pressure force on the outer edge of the disk-shaped side caps, so that the freely rotatable flywheel is fixed in position, the freely rotatable flywheel remains fixed in position as long as the applied Compressive force is kept constant. When the amount of applied compressive force is reduced, that is, as the applied compressive force decays, the disk-shaped side caps preferably return to the position as before application of the compressive force or, in other words, the disc-shaped side caps again move away from the freely rotatable swinging body as before application of the compressive force engaging compressive force. Therefore, the applied compressive force preferably corresponds to the force on the outer edge of the disk-shaped side caps which must be exerted to hold the side caps in the compressed position so that the freely rotatable swing body remains fixed in position. The decay of the applied compressive force therefore also corresponds to a release of the disc-shaped side caps, so that they return to their original starting position.

It is further preferred that at a low deflection f, that is, at a deflection of the disc-shaped side caps, which preferably maximally the distance B ₄ between the flywheel body (S) and the inner surface of the first disc-shaped side cap (K1) and / or the distance B. ₅ between the flywheel body (S) and the inner surface of the second disk-shaped side cap (K2) corresponds, in particular when the diameter of the disk-shaped side caps is less than or equal to the diameter of the flywheel body (S), an in Substantial elastic deformation takes place, so that after the loss of force, the disk-shaped side caps return to their original state. It is therefore preferred that the material from which the disc-shaped side caps are made is deflected by a small deflection / "preferably by 0.1 - 3.0 mm, by 0.3 mm - 2.0 mm, more preferably by 0, 5 mm - 1, 5 mm and most preferably by 0.8 mm - 1, 2 mm behaves elastic or visco-elastic or substantially elastic, so that the disc-shaped side caps are not plastically deformed or break.

It is therefore also preferred that the material from which the disc-shaped side caps are made is not made of a very elastic and soft material, that is preferably not made of a material with a small electricity module, in which already in holding the rotatable game body bending the disc-shaped side caps takes place, so that the disc-shaped side caps are movable at the outer edge even at a low attacking pressure force against the freely rotatable flywheel, so that the freely rotatable flywheel is fixed in position.

Therefore, it is preferable if the applied compressive force or the applied compressive force which is necessary for bending the disk-shaped side caps by a deflection f, wherein the deflection f preferably maximally the distance B ₄ between the flywheel body (S) and the inner surface of the first disk-shaped side cap (K1) and / or the distance B. ₅ between the flywheel body (S) and the inner surface of the second disk-shaped side cap (K2), in particular when the diameter of the disk-shaped side caps is less than or equal to the diameter of the flywheel body (S) is not smaller than 15 N, preferably, not smaller is greater than 14 N, more preferably not smaller than 13 N, further preferably not smaller than 12 N, more preferably not smaller than 1 N, and most preferably not smaller than 10 N, and most preferably not smaller as 5 N.

Several millions of these turn and stop cycles are possible with the play ring.

Another advantage of the rotatable game body of the present invention over the prior art finger gyros is that the disk-shaped side caps of the rotatable game body of the present invention provide a larger surface area for printing. The finger gyroscope of the prior art according to DE 20 2017 103 662 U1, CN 107 754 323 A, CN 107 395 815 A or US 9,914,063 B1 have cover caps which are largely completely concealed by the fingers when they are held. When the disc-shaped side caps have a diameter larger than the diameter of the centered ball bearing, preferably in the range of 0.5 times to 1.5 times, more preferably 0.5 times to 1.2 times, further preferably from 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times to 1.4 times, more preferably from 0.8 up to 1, 3 times, more preferably from 0.7 times to 1, 2 times, more preferably from 0.8 times to 1.2 times, more preferably from 0.7 times to 1, 1-fold, more preferably from 0.8 to 1, 1-fold, more preferably from 0.9 to 1, 1-fold, more preferably from 0.95-fold to 1, 1-fold, on Preferably, the 0.95 times to 1, 05 times the flywheel, the outer surfaces of the disc-shaped side caps can be printed preferably, so that the printed figures, motifs, shapes and text are not completely covered by the fingers who the. The advantage of printing the disc-shaped side caps over the printing of the lateral outer surfaces of a flywheel body is that the disc-shaped side caps do not rotate, that is not freely rotatable, so that the figures, motifs, images and text even during the rotation of the flywheel clear and are clearly visible. Thus, the finger gyroscopes of the prior art do not provide comparable surfaces that can be printed in which, during the use of these finger gyroscopes, ie while playing, the figures, motifs, images and text can be clearly seen during the rotation of the rotating body , Even with the finger gyroscope of the prior art according to CN 107 320 973 A, the covers are rotatable and rotatably connected to the rotating body covers, which therefore rotate with the rotating body. The depiction of figures, motifs, shapes, and text on non-rotating disc-shaped side caps enhances the enjoyment and enjoyment of printed surfaces during use of the rotatable gaming machine of the present invention, that is, during play, that is, during play Rotation of the freely rotatable flywheel body of the present invention. In preferred embodiments, the disc-shaped side caps of the rotary toy body of the present invention may be interchanged. Since in the prior art finger gyros the non-rotating cover caps are largely concealed by the fingers as they are held, and during rotation, figures, motifs, images and text on the outer lateral surface of the rotating body are not clear during rotation due to the rotational movement can be clearly seen, in an exchange of the caps in finger gyros from the prior art, no increase in the fun game causes. In the rotatable game body of the present invention, the figures, motifs, images and text are preferably not completely obscured when being held, so that a user can arbitrarily exchange the disk-shaped side caps as desired and with various disc-shaped side caps printed with figures, motifs, images and text can use. Thus, with the rotatable game body of the present invention, a rotatable game body can advantageously be provided which has individually printed outer surfaces of the disk-shaped side caps which do not rotate during use of the rotatable game body and thus provide pleasure during rotation of the rotatable game body, which many users especially kids have fun.

Another advantage of the rotatable game body of the present invention is that the disk-shaped side caps can be printed with figures, motifs, images, shapes and text in the form of one or more markers, which after printing and stopping the rotation of the freely rotatable swing body on a printed Field on the outer edge of the rotatable game body, in the case of a cylindrical outer shell on the cylinder surface or lateral surface, or can indicate. In the finger gyros of the prior art, such a mark is inevitably covered when holding with his fingers, or the user has to cumbersome raise his finger to detect which field could be selected. Since the rotating bodies of the prior art finger gyros are freely rotatable bodies, it is likely that the rotating body will inadvertently continue to move, especially when the user's fland or fingers are making such a finger gyration hold on, is moved. Therefore, with the rotatable game body of the present invention, the opposing disk-shaped side caps may preferably have a diameter in the range of 0.5 times to 1.5 times, more preferably 0.5 times to 1.2 times, more preferably from 0.7 times to 1.4 times, more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times to 1.4 times, more preferably from 0.8 times to 1, 3 times, more preferably from 0.7 times to 1.2 times, more preferably from 0.8 times to 1.2 times, more preferably from 0.7 times to 1.1 times -fold, more preferably from 0.8 to 1, 1-fold, more preferably from 0.9 to 1, 1-fold, more preferably from 0.95 to 1, 1-fold, more preferably from 0.95 times to 1.05 times the diameter of the rotatable flywheel body, a rotatable game body can be provided, with which easy and convenient fun-enhancing additional functions with the provision ung of disc-shaped side caps with larger surface areas which are preferably printable can be integrated into a game. The rotatable game body further has the advantage that the disc-shaped side caps are preferably movable against the freely rotatable flywheel body at the outer edge to fix the freely rotatable flywheel in its position, so that in contrast to finger gyros from the prior art, an unintentional rotation or movement of the freely rotatable flywheel body can be prevented because the fixed freely rotatable flywheel body can not rotate freely.

The disadvantages of the prior art finger gyros are, inter alia, that they are exclusively designed to bring about fun and enjoyment of the rotation of the rotating body. For this reason, the focus in providing the prior art finger gyroscopes is to provide rotating bodies which, upon rotation, provide additional effects, e.g. Show lighting effects with built-in LEDs. In its simplest form, the visual effect obtained with the prior art finger gyros is that the two or three or more "gyros" in the gyros have the two or three or more "gyros" during rotation more clearly and clearly distinguishable from each other and are delimited, so that for the user's eye, the rotating body with the two or three or more "gyros" appears circular and round.

The rotatable game body of the present invention has advantageous properties, since the disk-shaped side caps can be printed on the outer surfaces and the diameter of the disc-shaped side caps is preferably so large that figures, motifs, images and text are not completely hidden, but also that the outer Mantle of the flywheel body has one or more printable surfaces, as preferably on the outer edge of the outer shell, so the lateral surface, or the cylinder surface in the case of a cylindrical outer shell, so that the visual effects of the finger gyroscope of the prior art in the rotatable Game body of the present invention can be integrated. Thus, with the rotatable toy body of the present invention, it is preferable to provide the representation of figures, images, motifs and text during rotation, as well as visual effects by the rotation of the rotatable swing body simultaneously with a rotatable game body according to the invention. Surprisingly, it has been found that such a combination of printable non-rotating surfaces and printable rotating surfaces provides an enhanced and positive effect on the fun and enjoyment of playing with the rotatable gaming machine of the present invention.

With the provision of a freely rotatable flywheel body between two non-rotating opposing side caps having a diameter in the range 0.5 times to 1.5 times, more preferably 0.5 times to 1.2 times, more preferably 0 , 7-fold to 1, 4-fold, more preferably from 0.7 times to 1, 3 times, more preferably from 0.8 times to 1, 4 times, more preferably from 0.8 times to 1.3 times, more preferably 0.7 times to 1.2 times, more preferably 0.8. to 1, 2 times, more preferably from 0.7 times to 1, 1 times, more preferably from 0.8 times to 1, 1 times, more preferably from 0.9 times to 1, 1 times -fold, more preferably 0.95-fold to 1, 1-fold, more preferably 0.95-fold to 1, 05 times the diameter of the rotatable flywheel body, a rotatable game body is provided according to the invention, on the one hand easy to handle On the other hand, by combining the joy of a freely rotatable swinging body with the enjoyment of printable non-rotating outer surfaces that provide additional opportunities for enhancing gameplay, an increase in gaming fun with the rotatable gaming machine of the present invention is achieved. With these advantageous properties, the present invention therefore provides a rotatable game body with which, in particular, the fun of playing is maintained over a long period of time and the motivation and interest in playing with the rotatable game body is maintained over a long period of time or even increased. Furthermore, due to the advantageous technical properties of the rotatable game object according to the invention, pedagogically valuable functions can also be integrated into the game sequence with the rotatable game body, which bring about a positive and positive learning effect in addition to the joy of the game, especially in children. In some embodiments, the material from which the disc-shaped side caps are made may be a metal or a metal alloy, eg, steel, stainless steel having a high modulus of elasticity E. The force that needs to be expended to bend a material having a given geometric shape depends on the material constants of the material used, as well as the geometric shape and stress of the material. The force that needs to be expended to bend a disc-shaped side cap depends on where the force is acting. When the force acts perpendicular to the disc-shaped side caps, the required applied compressive force that must be applied to the disc-shaped side caps to be bent by the maximum deflection, least, when the pressure force at the maximum distance to the center of the side cap engages, so preferably on outer edge (R1 or R2) of the disc-shaped side caps (K1 or K2). The maximum distance to the center is therefore at the outer edge of a disc-shaped side cap. Therefore, the minimum amount of pressure applied to move the disc-shaped side caps against the freely rotatable swing body to fix the freely rotatable swing body in position depends on the diameter of the disc-shaped side cap, the diameter of the centered extension on the inner surface of a disc-shaped side cap, the mold the centered extension on the inner surface of a disc-shaped side cap, the thickness or width or fleas of the disc-shaped side cap as well as the material constants of the material is made from the disc-shaped side cap from. The pressure force that must be applied is the higher, the thicker or wider or higher the side cap is, the smaller the radius of the side cap and the stiffer the material is, for. B. has a high modulus of elasticity. If a material is bent, it can behave elastically behavior, non-elastic, visco-elastic or inelastic. So can one Material are plastically deformed at a certain deflection or break or elastically deformed at a certain deflection, so that after the elimination of the force, the material elastically returns to its initial state.

If the disc-shaped side caps have a diameter which is smaller than or equal to the diameter of the flywheel body, the disk-shaped side caps can only be moved so far against the freely rotatable flywheel body, that is to be deflected inwards, such as the distance B ₄ or B ₅ the inner surfaces of the disc-shaped side caps is to the flywheel body. Therefore, it is preferable if the disc-shaped side caps are not plastically deformed or broken at a deflection by the distance of the inner surfaces of the disc-shaped side caps to the flywheel body. Therefore, the distance between the disc-shaped side caps and the flywheel body must be considered. The diameter of the disc-shaped side caps is preferably in the range of 0.5 times to 1.5 times, more preferably 0.5 times to 1.2 times, more preferably 0.7 times to 1.4 more preferably from 0.7 times to 1.3 times, more preferably from 0.8 times to 1.4 times, more preferably from 0.8 times to 1.3 times, more preferably from 0.7 times to 1.2 times, more preferably from 0.8 times to 1.2 times, more preferably from 0.7 times to 1.1 times, more preferably from 0.8 times to 1, 1 times, more preferably from 0.9 times to 1, 1 times, more preferably from 0.95 times to 1, 1 times, more preferably from 0.95 times to 1, 05 times -fold the diameter of the flywheel. If the diameter of the disk-shaped side caps, for example, 1, 2 times the diameter of the flywheel body, so the disk-shaped side caps on the outer edge of the disc-shaped side caps with a deflection which is greater than the distances B ₄ and B _{5 are} deflected. It is preferred that the disc-shaped side caps are not plastically deformed even with this deflection and also do not break.

In a further preferred embodiment, the disk-shaped side caps and the flywheel body at a suitable distance, so that for example a perpendicular to the disk-shaped side caps inwardly directed force can preferably be exerted on the outer edge of the disc-shaped side caps, so that a braking effect of the rotation of the flywheel body becomes after the flywheel has previously been rotated. In an exemplary embodiment of the rotatable game body, the above-described force can be applied by compressing the game body at the outer edge of the side caps with two fingers. In a preferred embodiment, the rotationally offset freely rotating flywheel body is preferably decelerated by compressing the disk-shaped side caps on the outer edge of the disk-shaped side caps. It is preferred if at least a pressure force of 20 N must be exerted on the outer edges of the disc-shaped side caps, so that the rotating, freely rotating flywheel body is braked.

In other words, it is preferred that the disk-shaped side caps and the flywheel body have a suitable distance, so that the disc-shaped Side caps on the outer edge are movable against the freely rotatable flywheel to fix the freely rotating flywheel in position. "Locking" as used herein means that a flywheel previously set in rotation is braked until the free-rotating flywheel stops , as well as that a swinging body that is fixed, can not be set in rotation. In other words, a freely rotatable flywheel body is fixed, so its position is maintained. In an exemplary embodiment of the rotatable game body, a force acting perpendicular to the disk-shaped side caps may be exerted by compressing the game body at the outer edge of the side caps with two fingers. In a preferred embodiment, the flywheel body fixed by the compression of the disk-shaped side caps can not be set in rotation by the applied pressure force. Only when the disc-shaped side caps are no longer compressed, that is, when the applied pressure force decays, the disc-shaped side caps preferably take the position they had before applying the compressive force, that is, the disc-shaped side caps again the distance to the freely rotatable Take flywheel body as before applying the compressive force, so that the freely rotatable flywheel body is no longer fixed, that is again freely rotatable and thus can be set in rotation again.

Thus, the rotation of the flywheel body can be braked or fixed by squeezing the side caps on the outer edge of the side caps, it is preferred that the side caps are made of a material under a certain force, the one bending of the material and thus a bending of the disc-shaped side caps causes, that is, a deflection f causes the outer edge of the disc-shaped side caps, which are made of this material disc-shaped side caps are deformed substantially elastic and assume after termination or elimination of the force back to the original state. It is particularly preferred that the side caps are not plastically or permanently deformed by the compression, that is, by the applied compressive force. In other words, it is preferable that the material from which the disc-shaped side caps are made, upon compression of the side caps on the outer edge of the disc-shaped side caps to brake the rotation of the flywheel or to fix the flywheel, is elastically deformed and thus the disc-shaped Side caps are elastically deformed. It is further preferred that, when the inner surfaces of the disc-shaped side caps each have a distance B ₄ and B ₅ to the flywheel, the disc-shaped side caps by a perpendicular to the disk-shaped side caps inwardly directed force preferably acts on the outer edge of the disc-shaped side caps pressing force to the distance B ₄ and B ₅ bent inward, that is to be moved, that is to be bent in the direction of the flywheel or bent towards each other, that is movable against the freely rotatable flywheel, so that the disc-shaped side caps and the momentum body come into contact, that is, that the disc-shaped side caps are bent or moved so far in the direction of the flywheel that touch the disc-shaped side caps and the flywheel, so that a braking of the rotation of the flywheel is caused by frictional forces occurring after the flywheel body was previously set in rotation, and so that flywheel body is fixed in its position, whereby the disk-shaped end caps after completion or discontinuation of the force, that is, after the decay of the applied compressive force again assume the original state, in other words after completion or discontinuation of the action of force back the distance B ₄ and B ₅ to the flywheel, that is, return to the position as before applying the pressure. In other words, at least one of the disk-shaped side caps is preferably deflected at a deflection f by the distance B ₄ or B ₅ , that is to say that the disk-shaped side caps are not plastically deformed or broken in the case of a deflection f = B ₄ or B ₅ means that the material from which the disk-shaped side caps are made substantially elastically deflects at a deflection f = B ₄ or B ₅ when a compressive force acts on the outer edge of the disk-shaped side caps, the rotation of the freely rotatable swing body is decelerated or wherein the freely rotatable flywheel is fixed in position.

The present invention therefore particularly preferably relates to a rotatable toy body suitable for a children's game consisting of a freely rotatable flywheel body (S) arranged between two opposite disc-shaped side caps (K1) and (K2), wherein the flywheel body (S) has an outer casing (M) and a centered ball bearing (L), the first disc-shaped side cap (K1) has an outer edge (R1), an outer surface (F1) and on the inner surface (11) has a first centered extension (P1), the opposite second disc-shaped side cap (K2 ) has an outer edge (R2), an outer surface (F2) and on the inner surface (I2) a second centered extension (P2), and the projections (P1) and (P2) are adapted to engage the flywheel (S), wherein the disc-shaped side caps (K1) and (K2) on the outer edge (R1) and (R2) against the freely rotatable flywheel (S) are movable to the freely rotatable To fix swinging body (S) in its position.

A force on the outer edge of the disc-shaped side caps herein means that the force acting on the disc-shaped side caps perpendicular to the disc-shaped side caps acts on a point which is the maximum distance to the center the disc-shaped side caps, so corresponds to the outer radius of the disc-shaped side cap. If the disc-shaped side caps are cylindrical, the force at the outer edge of the disc-shaped side caps, so at a distance of the outer radius of the disc-shaped side caps can advantageously attack at each point of the outer periphery on the outer edge of the disc-shaped side caps. When the disc-shaped side caps have a triangular, quadrangular, pentagonal, hexagonal, octagonal or polygonal shape, preferably triangular, quadrangular, pentagonal, hexagonal, octagonal or polygonal shape is regular polygon, it is preferred that the applied compressive force on the outer edge of the disc-shaped side caps is applied at the maximum distance to the center. In the case of a regular polygon, as already described above, the corners of a polygon are all on an imaginary circle. Therefore, it is preferred that the engaging pressure force on the outer edge of the disk-shaped side caps engage the corners of the regular polygon, since the corners have the maximum radius to the center of the disk-shaped side caps. Since the compressive force acting on the outer edge of the disc-shaped side caps can advantageously engage at any point on the outer circumference of the disc-shaped side caps in the case of a cylindrical outer shell of the freely rotatable flywheel, preferably in the form of a flash cylinder with a constant wall thickness (W) and a constant outer radius, is a cylindrical outer jacket, preferably in the form of a flea cylinder, particularly preferred.

The present invention therefore preferably relates to a rotatable game body suitable for a children's game consisting of a between two opposite disk-shaped side caps (K1) and (K2) arranged freely rotatable flywheel body (S), wherein the flywheel body (S) has an outer jacket (M) and a Centered ball bearing (L), the first disc-shaped side cap (K1) has an outer edge (R1), an outer surface (F1) and on the inner surface (11) has a first centered extension (P1), the opposite second disc-shaped side cap (K2) an outer edge (R2), an outer surface (F2) and on the inner surface (I2) has a second centered extension (P2), and the projections (P1) and (P2) are adapted to engage the flywheel (S), wherein the disc-shaped side caps (K1) and (K2) on the outer edge (R1) and (R2) against the freely rotatable flywheel (S) are movable to the freely rotatable swing k The free rotatable flywheel (S) with the outer shell (M) is cylindrical and the outer cylindrical surface of the cylindrical flywheel (S) is flat and printable, wherein preferably the wall thickness (W) of cylindrical outer jacket (M) is constant, wherein preferably the outer radius of the cylindrical outer jacket (M) of the freely rotatable flywheel body (S) is constant.

If the first and second disc-shaped side caps have a triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal or polygonal shape, preferably in the form of a regular polygon, then it is preferred that the corners of the regular polygon of the first and second disc-shaped side caps are superimposed so that the applied compressive force on both sides of the rotatable flywheel body can engage at opposite locations.

It is therefore particularly preferred if the distance B ₄ between the inner surface of the first disc-shaped side cap and the flywheel body and the distance B ₅ between the inner surface of the second disc-shaped side cap and the flywheel body in front of the perpendicular to the disc-shaped side caps inwardly directed force, preferably on the outside Edge of the disk-shaped side caps, preferably at the maximum distance to the center of the disk-shaped side caps, So the outer radius of the disc-shaped side caps and after completion or elimination of this force remains constant or the same. That is, it is preferable that B ₄ (before force) = B ₄ (after force) and B ₅ (before force) = B ₅ (after force). It is therefore preferred that the disk-shaped side caps are reversibly movable by an applied pressure force against the freely rotatable flywheel body at the outer edge to fix the freely rotatable flywheel in its position.

It is preferred that an engaging compressive force of at least 20 N perpendicular to the disc-shaped side caps, preferably on the outer edge of the disk-shaped side caps, be applied so that the disc-shaped side caps at least by the distance of the distance between the disc-shaped side caps and the freely rotatable swing body, the is to be deflected by the distance B ₄ and B ₅ , so that a deceleration of the rotating flywheel body is effected or wherein the freely rotatable flywheel body is fixed in position.

Technically relevant skill characteristics may be determined by one skilled in the art by methods known in the art, and a stress-strain diagram may be made for a given material. In a stress-strain diagram, a distinction is made between different regions: the linear elastic region, in which the expansion of the stress is proportional and thus the Flookesche law applies, the non-linear-elastic region in which the deformation is still reversible, that is elastic but is no longer proportional to the stress and the elastic-plastic region in which the deformation is partially plastic, that is, irreversible. If the elastic limit is exceeded, permanent deformation occurs in a component or material. It is therefore preferred that the disc-shaped side caps are reversibly movable against the freely rotatable flywheel body at the outer edge by an applied pressure force in order to fix the freely rotatable flywheel in its position, wherein the elastic limit of the material of the disk-shaped side caps at a deflection f of the disc-shaped Side caps on the outer edge of the side caps in the direction of the freely rotating flywheel body is not exceeded.

The strength of a material describes its resistance to mechanical stress before failure, and is given as the stress s (force per cross-sectional area). The failure may be an impermissible deformation, in particular a plastic or permanent deformation or a fracture. Depending on the type of material, material condition, temperature, load and load speed different strengths can be achieved. The strength of a material thus depends on the material itself, on the time course of the stress and on the type of stress.

The stiffness of a material describes the relationship between strain and mechanical stress and thus the resistance of a body to elastic deformation by a force or moment (bending moment or torsional moment). The rigidity of a component depends not only on the elastic properties of the material (the modulus of elasticity), but also on the geometry of the component. The Bending stiffness is the product of the modulus of elasticity (E) of the material and the area moment of inertia (I) of the cross section. The curvature of the body is proportional to the applied bending moment and inversely proportional to the bending stiffness. The term bending moment refers to a moment that loads a thin (eg bar) or thin component, eg a plate, and consequently bends it. In order to determine the effects of a moment load, the course of the bending moment is considered, for example in the case of a beam, the beam longitudinal orientation. In general, the deformation or bending line of the component and the existing mechanical stresses or bending stresses are determined so that they can be compared with the maximum permissible stresses or strengths of the material. For example, a beam clamped on one side can be loaded at the free end at a distance L by a force F as a point load P. Cross-section and material properties are preferably constant along the beam. The bending moment is zero at the point of introduction of the force and increases linearly up to the clamping point to a maximum value M = FL.

The elasticity is the property of a body or material to change its shape under force and to go back to its original form when the acting force ceases. A distinction is made between the linear-elastic behavior described by Flookesche's law, it generally occurs with small deformations, as well as the non-linear elastic behavior, in which the stress depends non-linearly on the deformation. Remains after removal of the deflecting forces a deformation, it is called elastic flysteresis. For all materials, there is a limit to the range of elasticity beyond which non-elastic behavior is observed. The modulus of elasticity (E), also modulus of elasticity, is a material characteristic value from material technology which describes the proportional relationship between stress and strain in the deformation of a solid body in linear-elastic behavior. The modulus of elasticity is the proportionality constant in Flookeschen's law. The amount of elastic modulus is greater, the more resistance a material opposes its elastic deformation. A high modulus (e.g., steel) material component is stiffer than a component of the same construction made of a low modulus material (e.g., rubber). The modulus of elasticity is defined as the slope of the graph in the stress-strain diagram for uniaxial stress at infinitesimal distortion change at dielectric strength. Most materials have at least a small linear elastic range, this is also referred to as Flookescher range. Real materials have a limit of elasticity within which they elastically deform and beyond which dissipative processes such as fractures occur. The Flookesche law describes the elastic deformation of solids, if their deformation is proportional to the applied load (linear-elastic behavior). This process is typical of metals, if the load is not too large, and for hard, brittle materials such as glass, ceramics, silicon often to breakage.

The yield strength is a material characteristic value and refers to that stress up to which a material or material is subject to uniaxial and torque-free tensile stress no permanent plastic deformation shows: if the yield strength falls below the elastic limit, the material returns elastically to its original shape after unloading, and if the yield strength is exceeded, a change in shape remains; in the case of a tensile test, therefore, an elongation, ie, a permanent curvature. The characteristic values corresponding to the yield strength for other types of material stress are the crimping, bending and torsion limits, which are also summarized under the umbrella term flow and elasticity limits. It is therefore preferred that the yield strength or bending limit of the material of the disk-shaped side caps is not exceeded in the direction of the freely rotatable flywheel body at a deflection f of the disc-shaped side caps on the outer edge of the side caps.

The elastic limit of a material is the magnitude of the mechanical stress below which the material is elastic, i. it returns to its original shape when the load is removed (reversible deformation). When the elastic limit is exceeded, irreversible stretching or compression or plastic deformation occurs. The elastic limit values are used in addition to other material parameters for the calculation and determination of the strength and stability of mechanical constructions.

Surprisingly, it has been found that a lower engaging compressive force must be applied to the outer edge of a disc-shaped side cap to bend or move a disc-shaped side cap at the outer edge by the distance of the distance between the swinging body and the inner side of the side caps, or around the distance bend or move the distance B ₄ and B ₅ and thus to decelerate the rotating flywheel or to fix the freely rotatable flywheel in position, the smaller the width of the disc-shaped side caps, the smaller the distance between the side caps and the freely rotatable flywheel body and the further the point of application of the applied pressure force to the center of the disc-shaped side caps is removed and the greater the difference of the outer diameter of the disc-shaped side caps to the outer diameter of the centered extensions.

An important role therefore also plays the diameter of the centered extensions on the inside of the disc-shaped side caps. For example, if the diameter of the centered extensions is assumed to be punctiform, the distance between this point and the point of application of the applied compressive force, which in this approach corresponds to the outer radius of the disc-shaped side caps, will be used to calculate the applied force at the outer edge of a disc-shaped side cap a given material. That is, at an applied compressive force at the outer edge of the disc-shaped side cap between the center and the distance at which the force acts as the attacking point force, is referred to as a length. In such an approximation, assuming that the centered extensions are punctiform, the maximum length to the point of application of the applied compressive force is the length of the outer radius, ie half the diameter of the disc-shaped side caps. When the diameter of the centered extension is larger and, for example, an outer diameter has, for example, which corresponds to half the diameter of the disc-shaped side caps, so the disc-shaped side caps have a 50% larger diameter, or have a 2 times larger diameter than the centered extensions, then the length corresponds to the point of attack of the compressive pressure force half the outer radius the disc-shaped side caps. It is known to those skilled in the art that when bending a cantilevered beam or a cantilevered plate, a greater force must be applied the smaller the length of the beam or plate is. A one-sided clamped beam or a one-sided clamped plate can be loaded only at the non-clamped end or side with an applied compressive force, so that a bending takes place. In the rotatable game body of the present invention, the disk-shaped side caps on the inner surfaces each have a centered extension, which are each suitable to engage in the flywheel body, preferably engage positively in the flywheel body. The disk-shaped side caps are thus centered clamped over the centered extensions and can be loaded on the non-clamped outer edges with an attacking compressive force, so that a bending takes place. The bending stress generated in contrast to tensile and compressive tests in the body cross section a variable stress and strain. On the upper side of the disc-shaped side caps thus creates a tensile stress and on the underside of a compressive stress to which the disk-shaped side cap reacts with a compression or elongation of the edge fiber. The maximum elongation is also called edge fiber elongation. Therefore, the marginal fiber strain e at the deflection f of the disc-shaped side caps on the outer edge of the disc-shaped side caps must be calculated. It is preferred that the marginal fiber strain e is below the maximum allowable strain s _zui .

That is, transferred to the rotatable toy body of the present invention, the greater the outer radius or diameter of the centered extensions, the greater is the applied compressive force that must be applied to the outer edge of the disc-shaped side caps to allow a disc-shaped side cap to wrap around the outer edge given deflection f can be moved or can be bent. That is, the smaller the length, the greater the amount of the applied compressive force, and the greater the applied compressive force, the sooner plastic deformation or breakage of material occurs. Thus, the disc-shaped side caps on the outer edge reversibly or elastically to a deflection f can be moved or deformed, so the diameter of the disc-shaped side caps and the diameter of the centered extensions and thus the diameter of the second central recess must be observed.

Therefore, it is preferred if the diameter of the disk-shaped side caps is at least twice as large as the outer diameter of the centered extensions of the disk-shaped side caps. It is also preferred that the diameter of the disk-shaped side caps is at least one third larger than the diameter of the centered extensions of the disk-shaped side caps. It is also preferred that the diameter of the disc-shaped side caps at least one third larger than the diameter of the second central recess of the flywheel body. Therefore, it is preferred that the diameter of the disc-shaped side caps be at least 50%, more preferably at least 40%, and most preferably at least 30% greater than the diameter of the centered extensions of the disc-shaped side caps. It is also preferred that the diameter of the disc-shaped side caps is at least 50%, more preferably at least 40%, and most preferably at least 30% greater than the diameter of the second central recess of the flywheel body. Therefore, it is preferred that the disc-shaped side caps have at least 1.5x, more preferably at least 1.4x, and most preferably at least 1.3x greater diameter than the diameter of the centered extensions of the disc-shaped side caps. It is also preferred that the disc-shaped side caps have at least 1.5 times, more preferably at least 1.4 times, and most preferably at least 1.3 times larger diameter than the diameter of the second central recess of the flywheel body.

A non-exhaustive overview of the material properties Young's modulus, yield stress and tensile strength for some materials such as metal alloys and polymers (plastics) is shown in Table 1. It is known to those skilled in the art that these values depend on the exact composition and nature of the particular material.

Table 1: Overview of Young's modulus, yield stress and tensile strength of some materials

Due to their structure, thermoplastics are divided into amorphous and semi-crystalline polymers. Plastics with an amorphous structure are usually transparent and tend to be susceptible to stress cracking. Semi-crystalline plastics are opaque and usually tough. The thermoplastic materials are further subdivided due to their temperature resistance: high-temperature plastics are suitable for a continuous service temperature of over 150 ° C, engineering plastics are durable at temperatures between 100 ° C and 150 ° C and have good mechanical properties, standard plastics such as polypropylene or polyethylene can be used permanently at temperatures below 100 ° C. Through a targeted incorporation of fillers, the properties of the plastics can be adapted to the desired field of application, such as e.g. with reinforcing fibers such as glass fibers, with which mainly an increase in the strength values is achieved, in particular the tensile strength, but also other characteristics such as compressive strength and heat resistance. Carbon fibers can be used as an alternative to glass fibers to increase strength. Through the incorporation of pigments and dyes, tailor-made color settings can be made for engineering plastics. With the addition of UV or heat stabilizers, effects can be reduced by environmental factors or by prolonged high heat loads, which can lead to discoloration or impairment of the mechanical properties of many plastics.

In general, in the state of the art in a standardized or standardized tensile test, mechanical characteristic values are determined which serve to assess the behavior of plastics in the case of short-term, uniaxial loading. Important for the selection of a plastic in addition to the behavior during tension and elongation, the temperature and the time of loading. The tensile stress s is the tensile force related to the smallest measured initial cross-section of the specimen at any point in the experiment. The tensile strength O _B is the tensile stress at maximum force. The tensile strength O _R is the tensile stress at the moment of tearing. The yield stress Os is the tensile stress at which the slope of the force-length change curve becomes zero for the first time. The elongation e is the change in length AL related to the original measuring length L _{0 of} the specimen at any time during the experiment. The elongation at maximum force is denoted by E _B , the elongation at break by E _R and the yield strain by Es. It should be noted that the elastic modulus E is only at the lowest part of the stress-strain diagram Plastics has a linear curve. Hooke's law is valid in this area, which states that the quotient of stress and strain (elastic modulus) (E = s / e in MPa or in N / mm ² ) is constant.

Hereinafter, with some simplifying approximations, the effects of the outer radius of the disc-shaped side caps, the outer radius of the centered extensions, the width of the disc-shaped side caps, the distance of the inner surfaces of the disc-shaped side caps to the freely rotatable swing body and the material are made from the disk-shaped side caps on the attacking pressure force by the disc-shaped side caps on the outer edge are reversibly moved against the freely rotatable flywheel body to fix the freely rotatable flywheel in position, shown. Although a cantilevered beam or cantilevered plate is hereinbelowed for simplicity, it will be understood by those skilled in the art how the relationships described below may be applied to a disk-shaped side cap of the rotary toy body of the present invention. Since approximations are made in the following for the sake of simplification, the physical formulas shown below and the resulting forces do not correspond to the absolute real forces which are applied to the center-mounted disc-shaped side cap which is moved against the freely rotatable flywheel body at the outer edge of the disc-shaped side cap freely rotatable flywheels to fix, must be spent or can occur.

As an approximation of a cantilevered beam or a cantilevered plate, which is deflected under single load F, assumed The bending theory provides for the beam or plate with a constant cross section, the deflection or deflection f

f = F. L ^3/3 EI (I)

with f = deflection, F = force, L = length of beam / plate, E = modulus of elasticity,

I = area moment of inertia. The product of the modulus of elasticity E and the axial area moment of inertia I for the bending axis is bending stiffness E I. Therefore, the applied compressive force to bend the cantilevered beam by a deflection f results from the above equation (I):

F = 3 f _* EI / L ³ (II)

For a rectangular plate clamped on one side, the following equation (III) can be used for the area moment of inertia:

I = bh ^3/12 (III)

with I = area moment of inertia, b = diameter of the cantilevered plate, h = width or height of the cantilevered plate.

After substituting equation (III) into equation (II) and assuming that the diameter is b = 2r and L = r, where r is half the length of the plate representative of the outer radius of a disc-shaped side cap and in FIG Assuming that the centered extension is point-shaped and the outer radius of the centered extension is therefore negligibly small, equation (IV) results: F = 0.5 f E h ³ / r ² (IV)

If the centered extension is not punctiform and has an outer radius r, equation (V) results:

F = 0.5 f E rh ³ / (r - r _f ) ³ (V)

By way of example, with a deflection f of 1 mm and a width of the plate of 1 mm, which is assumed to be representative of the width of the disc-shaped side cap, and a material having a modulus of elasticity of E = 4000 N / mm ² , such as, for example Plastic, results in an outer radius of a disk-shaped side cap of, for example, 14.5 mm approximately according to equation (IV) an attacking compressive force F = 9.5 N. Assuming that the centered extension has an outer radius of 6 mm results according to equation (V), a force of F = 47.2 N. Assuming a 20% larger outer radius of a disc-shaped side cap, there is approximately a force of F = 23.5 N for the applied compressive force according to equation (V) If a 20% smaller outer radius of a disk-shaped side cap is assumed, the force of F = 132.1 N is approximately equal to the applied compressive force according to equation (V). Therefore, approximately from equation (V), equation (VI), taking into account the variable x, results as an enlargement or reduction factor of the outer radius of the disc-shaped side cap:

F = 0.5 f E xrh ³ / (x r - r _f ) ³ (VI)

The exemplary illustrated calculated applied compressive forces necessary to move a disc-shaped side cap at the outer edge against a freely rotatable flywheel to fix the freely rotating flywheel in position clearly demonstrate how sensitive the applied compressive force is to the technical proportions of the rotatable game body, such as the diameter, width, fleas and distances, as well as on the material characteristics depends. These example calculations clearly illustrate how the amount of force required to apply a compressive force increases to move a disk-shaped side cap against a freely rotatable swing body when the outer radius of the centered extensions is increased or the outer radius of the disk-shaped side caps is reduced. It is obvious that the amount of the applied compressive force increases with a material having a higher modulus of elasticity used. The amount of the applied compressive force also increases significantly as the distance between the disk-shaped side caps and the flywheel increases, that is, when the deflection is increased.

The permissible deflection f can be calculated as a function of the permissible strain e _to i of the material used. It is preferable that this allowable deflection f is not exceeded upon compression of the disc-shaped side caps.

The permissible strain e _to i or stress o _ZUi at a single short-term deflection at 23 ° C can be estimated using the following rule: almost the yield strain in semi-crystalline thermoplastics, about 70% of the yield strain in amorphous thermoplastics and about 50% of the elongation at break in glass fiber reinforced Thermoplastics. With frequent short-term operation, it is recommended that approximately 60% of the once-permissible values be assumed. For long-term or continuous loads, there is a risk of stress crack formation in amorphous materials. For amorphous materials it is known that at strains below about 0.5%, the risk of stress cracking is significantly lower. The maximum marginal fiber strain e _to i can also be roughly calculated. For brittle materials, approximate elongation at break is valid. _BmCh = Elongation At _break, and thus e _to i = 0.5 _l _Breakage · For tenacious materials, approximate elongation at break applies £ _BmCh > 2 Elongation At _stretch and thus E _TO I = 0.8 It will _stretch - For a non-exhaustive and non-limiting selection of some plastics, the allowable strains for short-term and long-term loads are given as a guideline (in%) in Table 2.

Table 2: Permissible strains (in%) for short-term and long-term loading of some selected materials (plastics)

The deflection force can be calculated according to the geometric rigidity (cross-sectional configuration), the permissible elongation and the material stiffness (modulus of elasticity). If the strains occurring are outside the proportionality range of the stress-strain curve, the so-called "secant modulus E _s ", the strain-dependent modulus of elasticity, should be used instead of the elastic modulus for the determination of the deflection force. It is known to the person skilled in the art how the strain-dependent modulus of elasticity can be determined from a stress-strain diagram for a given material, in particular for a plastic. If a test specimen is subjected to a uniaxial tensile test, different stress-strain curves result depending on the type of plastic. While amorphous thermoplastics (polystyrene, PMMA) have a comparatively brittle mechanical material behavior, semicrystalline thermoplastics (PE, PP) show ductile, ductile behavior at room temperature. The reason lies here in that the amorphous thermoplastic is used at temperatures below the glass transition temperature. The material behaves here hard-brittle. By contrast, the semicrystalline thermoplastic is used below the crystalline melting temperature of the crystalline structures and above the glass transition temperature of its amorphous regions. While the crystalline regions create rigidity, the amorphous regions provide the ductile-tough elastic properties. Although plastics have a pronounced nonlinear viscoelastic behavior and also plastic strains when a certain load level is exceeded, the approach of a linear elastic material model can nevertheless be sufficient under short-term loading.

For the determination of the marginal fiber strain e, the following equation (VII) can be used for a cantilevered plate or cantilevered beam and approximately for a disc-shaped side cap:

e = 3 fh / 2 L ² (VII)

with f = deflection, L = length of the beam / plate, h = width or height of the cantilevered plate. This results in a permissible deflection f at an allowable elongation _{zu zui} by changing the equation (VII):

f = e 2 L ^2/3 h (VIII)

Thus, for linear (visco) -elastic material models, given a given allowable elongation, the maximum allowable deflection can be approximated using equation (VIII). This offers the possibility of uncertainty in knowing the correct material model or as in a linear-elastic case, if the modulus of elasticity is not exactly known. or if e.g. There is no stress-strain curve to estimate the permissible deflection, since the strain is purely geometrical with equation (VII) and is independent of the modulus of elasticity. However, if a material model with irreversible effects is used (e.g., an elasto-plastic material model), locally irreversible effects will occur depending on the stress.

For example, a rotatable play ring may be provided of a plastic, wherein the width of the disc-shaped side caps is 1 mm, and wherein the difference of the outer radius of the disc-shaped side caps and the outer radius of the centered extensions is 10 mm. If the material from which the disk-shaped side caps are made has a permissible elongation for short-term loads of, for example, 4.0%, then according to equation (VIII) a permissible deflection of 2.7 mm and for long-term loads an allowable elongation of, for example, 2.0 % is given, then results according to equation (VIII) an allowable deflection of 1, 3 mm. Thus, it would be particularly preferred for this example that the maximum deflection, preferably a deflection in the region of the distance B ₄ or B ₅ between the inner surfaces of the disk-shaped side caps and the freely rotatable flywheel, is less than or equal to 1, 3 mm or a maximum of 2 , 7 mm is.

With the approximations shown above, one skilled in the art will be able to estimate what technical proportions of diameter, spacing, width, and material will be suitable for providing a rotatable toy body of the present invention so that the disc-shaped side caps (K1) and (K2) on the outside Edge (R1) and (R2) are movable against the freely rotatable flywheel (S) to fix the freely rotatable flywheel (S) in position, wherein the disc-shaped side caps (K1) and (K2) at the outer edge (R1) and (R2) can be moved, in particular preferably reversibly, against the freely rotatable flywheel (S) by an applied compressive force in order to fix the freely rotatable flywheel (S) in its position.

Therefore, the present invention preferably relates to a rotatable game body suitable for a children's game consisting of between two opposite disc-shaped side caps (K1) and (K2) arranged freely rotatable flywheel body (S), wherein the flywheel body (S) has an outer shell (M) and a Centered ball bearing (L), the first disc-shaped side cap (K1) has an outer edge (R1), an outer surface (F1) and on the inner surface (11) has a first centered extension (P1), the opposite second disc-shaped side cap (K2) an outer edge (R2), an outer surface (F2) and on the inner surface (I2) has a second centered extension (P2), and the extensions (P1) and (P2) are adapted to engage the flywheel (S), wherein the disc-shaped side caps (K1) and (K2) on the outer edge (R1) and (R2) against the freely rotatable flywheel (S) are movable to the freely rotatable swing (S) to fix in position, wherein the disc-shaped side caps are made of a plastic, preferably made of a thermoplastic material, preferably made of a plastic selected from the group of acrylonitrile-butadiene-styrene copolymer (ABS), cellulose acetate ( CA), ionomers, polyamides (PA), polycarbonates (PC), polyetheretherketone (PEEK), polyethylene (PE), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polyoxymethylene (POM), polypropylene (PP), polystyrene (PS), Polyurethane thermoplastics, polyvinyl chloride (PVC), teflon (PTFE) or polybutylene terephthalate (PBT) are made, preferably made of a plastic with a permissible elongation for short-term loads of at least 4.0% or with a permissible elongation for long-term loads of at least 2 , 0% are made and in particular preferably made of polyoxymethylene.

B. not solve by gravity alone again from the second central recess of the centered ball bearing.

The first and second extensions on the inner surfaces of the disc-shaped side caps, as shown in the embodiments described hereinbefore, may preferably also have different shapes. Thus, a centered extension on the inner surface of a disc-shaped side cap, for example, be cylindrical or in the form of a triangle, quadrangle, pentagon or a regular polygon. The portion of the centered extension on the inner surface of a disc-shaped side cap in the distance of the inner surface of the disc-shaped side cap and the flywheel, so for example, the first stage of a two-stage extension may have a different outer shape, as the part of the extension, which has an outer diameter , which corresponds to the outer diameter of the second central recess of the centered ball bearing, that is, the second stage of a two-stage extension, so that this part of the centered extension can engage positively in the second central recess of the centered ball bearing.

The preferred embodiments described above, wherein the centered extensions have two stages as two-stage extensions, represent here only one way to realize a defined distance between the flywheel body and the inner surfaces of the side caps. In some further preferred embodiments, spacers may also be present on the inner surface of the disc-shaped side caps in a defined diameter. These spacers preferably have a length which corresponds to the lengths of the first stages of the two-stage extensions as described above. For example, in an exemplary embodiment, the first centered extension has spacers on the inner surface that are within a range of the diameter of the disk-shaped side cap that corresponds to the diameter of, for example, the inner ring of the centered ball bearing. The above-described embodiments wherein the two-step centered projections are in the form of two-step extensions or the disk-shaped side caps may have spacers for all the above-described embodiments of the centered extensions such that the first centered extension engages the second central recess of the ball bearing and the second Centered extension engages in the located in the second central recess of the centered ball bearing first extension, as well as that the first centered extension engages the second central recess of the centered ball bearing and the second centered extension in the second central recess of the centered ball bearing as well as in located in the second central recess of the centered ball bearing located first centered extension and as well as that the first and the second centered extension each in the second central recess of the centered Kugella intervene without interlocking.

Such a connector can be easily achieved by a material thickening and appropriate dilution of material. For example, a material thickening or punctiform or circular elevations may be centrally provided on the outer surface of the second centered extension which engage fittingly in a corresponding recess on the inner surface of the first centered extension. To solve this connection, ie to insert the second centered extension firmly seated in the first centered extension, a minimum pressure force of 20 N is required. Likewise, to release this connection, a tensile force of at least 20 N is needed. The connector described above is only one way to realize a locking mechanism. Thus, other methods known from the prior art can be used, so that the flywheel body, the first disc-shaped side cap, as well as the second disc-shaped side cap do not fall apart after they have been assembled to the rotatable game body according to the invention. Thus, it may also be preferred that this connection can be realized by a frictional assembly, for example when the central recess of the first centered extension has a thread, in that the second centered extension can be screwed in like a screw. In some embodiments, it may be preferred that the mated parts of the rotatable toy body can no longer be disengaged, for example, one of the two disk-shaped side caps may be so assembled with the flywheel, for example, glued with a suitable adhesive, that these two parts of the rotatable toy body are no longer to be solved, in particular no longer solve with a tensile force of 20 N. For example, in these embodiments, it may be preferred that only one of the disc-shaped side caps can be released and replaced with a tensile force of 20N. In a preferred embodiment, the first centered extension may engage the second central recess of the centered ball bearing, the first centered extension of the first disc-shaped side cap having a central recess into which the second centered extension of the second disc-shaped side cap can engage positively and wherein the first disk-shaped side cap and the centered ball bearings can no longer be separated from each other and wherein the second extension can engage positively in the central recess of the first extension. However, it is particularly preferred that the composite disk-shaped side caps can be released again from one another and also from the flywheel body under the action of force. This is particularly preferred if, for example, the flywheel body or one or both of the disk-shaped side caps of the rotatable game body are to be exchanged. In an exemplary embodiment, various flywheels and various disc-shaped side caps are provided which may be assembled together by a user in any combination.

Thus, it is preferred that the second centered extension (P2) of the second disc-shaped side cap (K2) engages in the first centered extension (P1) of the first disc-shaped side cap (K1) or the second centered extension (P2) of the second disc-shaped side cap (K2). K2) in engagement with the first centered extension (P1) of the first disc-shaped side cap (K1), such that it requires a compressive force of at least 20 N to make the connection and requires a tensile force of at least 20 N to make that connection to separate again.

Thus, the side caps can be replaced independently, it is preferred that the first centered extension is adapted to engage in the second central recess of the centered ball bearing and the second centered extension is adapted to engage in the second central recess of the centered ball bearing, wherein the centered extensions do not mesh with each other. It is preferred if the first centered extension engages the second central recess on the first side of the centered ball bearing and the second centered extension engages the second central recess on the second side of the centered ball bearing.

B. printed with different characters or the numbers from 1 to 6. Thus, this exemplary embodiment of a rotary game body, when printed with the numbers from 1 to 6, can be used like a cube. The flywheel is rotated by a user in rotation and z. B. with a finger stopped with the field on which the user's finger slows down the flywheel, represents the number that a user has "diced". On the other hand, when the outer surface of the outer skirt of the outer shell is printed with playing pieces or actions, the user can select a play figure or an action by stopping the rotating swing body.

In some preferred embodiments of the rotatable game body according to the invention, further components which generate, for example, acoustic and / or visual signals can be integrated into the flywheel body or into the two disk-shaped side caps. Suitable components which are suitable for a visual signal generation are, for example, light-emitting diodes (LEDs) which can be integrated, for example, in one or more recesses of the outer shell of the flywheel body, of the flywheel body or of the disk-shaped side caps. In a preferred embodiment, for example, a plurality of LEDs with different luminous colors can be incorporated in the outer shell of the flywheel body. Suitable components suitable for acoustic signal generation, as in the case of the LEDs, may be components which have acoustic signals rather than visually perceptible illumination, or are integrated, for example, such that an airflow flows through the component during rotation, with an audible signal is produced. Such components which generate acoustic or visual signals, more preferably generate them only upon rotation of the flywheel body, are known in the art and those of ordinary skill in the art, having the benefit of the present disclosure, are capable of producing acoustic and / or visual Select signals to integrate this in the rotatable game body. figure description
